Tip for advertising marketers: Don’t come across as a stalker

The Twingo. Little did its creators know it would become the cause of so much marital strife

From article:

Hundreds of angry Dutch women have complained to car manufacturer Renault after receiving handwritten letters purporting to come from a unknown admirer who called them "darling", suggested meeting soon for a drink and signed themselves "lots of love, M".

Some 30,000 letters were sent out – and Renault is now writing 30,000 apologies.

The letter was in fact part of an advertising campaign for a new version of their car, the Twingo, to be launched next month in the Netherlands where it has proved a particularly big seller.
